In 1665 Fortunio Liceti published an illustrated edition of his work De Monstris. Supposedly a work exploring deformities in nature, as you can see from the illustrations his monsters were quite fanciful. Not that it really explains his made-up monsters, he explained it as nature being like an artist that worked with what it had. As he said, "It is said that I see the convergence of both Nature and art because one or the other not being able to make what they want, they at least make what they can."
